Like the idea of driving down 4G chip costs. I also wonder, why in the world adding 4G adds ~150$ to device cost. But not sure, about the prospects of a 4G chip without 3G/2G . Most often, your network coverage for 4G is limited. Premium vendors like Apple samsung is unlikely to opt for such a device. If you dont move around much, and lives a area with good 4G coverage. Then it might make sense to get a 20$ 4G chip device vs 150$ 4G/3G/3G chip device.

It seems as though all of this is really riding on cellular providers to adopt this. All of today's newer phones provide LTE. What manufacturer would want a phone that doesn't provide Wifi and 3g too?..

I'd love to read a discussion about whether Wi-Fi, 3G or LTE is the most preferred link of choice for IoT and M2M.
I know its horses for courses, but isn't the general hierarchy of preference:
Wi-Fi: Cheap and fairly widely available or easily deploy-able
3G: Nearly as cheap if available
LTE: Least cheap, least available

In conjunction with unveiling of EE Times’ Silicon 60 list, journalist & Silicon 60 researcher Peter Clarke hosts a conversation on startups in the electronics industry. One of Silicon Valley's great contributions to the world has been the demonstration of how the application of entrepreneurship and venture capital to electronics and semiconductor hardware can create wealth with developments in semiconductors, displays, design automation, MEMS and across the breadth of hardware developments. But in recent years concerns have been raised that traditional venture capital has turned its back on hardware-related startups in favor of software and Internet applications and services. Panelists from incubators join Peter Clarke in debate.
